The Pfadfinder Joeys had a rather spectacular evening recently, making milk cartons in pizza ovens.
First they made their dinner by rolling their pizza ingredients into a wholewheat wrap. This in turn was sealed up in silver tin foil.
The tin foil dinner was then popped into an empty one-litre cardboard milk carton.
We had a safety lesson in lighting matches and caring for a fire safely, of course, and then with great excitement we lit our cartons and let them cook our dinner!
